FEEDING DEVICE FOR ANNULAR BODIES.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed August 10, 1918. Serial No. 249,366.

Be it known that I, AxEL GUSTAF EMAN- UEL HULTGREN, a subject of the King of Sweden, residing at Gottenborg, in the Kingdom of Sweden, have invented new and useful Improvements in Feeding Devices for Annular Bodies, of which the following is a specification.

This invention relates to feeding devices for. annular bodies, particularly track-rings for ball and roller bearings.

The primary object of the invention is the provision of a feeding device of the kind aforementioned in which the annular manner from a position in which they are cepable of moving in axial direction to a.

, position in which they move at right angles to said direction, the first named movement being a sliding movement, whereas the latter one is a rolling movement. In the starting position the plane side surfaces of the bodies bear, preferably, against each other. while in the final position their cylindrical outer surfaces are in contact with each other.

The device is especially adapted for use in machines, furnaces or the like to which rings are supplied continuously for further treatment.

For the purpose mentioned above the device consists, chiefly, of a magazine in which the rings are placed with the plane side surfaces facing each other and in which they are caused to perform a sliding movement in axial direction, a channel or the like being connected with the magazine, the bottom of said channel being so formed that the rings, when moving thereon, are passed successively to a position in which they move at right angles to the axial direction. Furthermore, the device comprises means for passing the rings from the magazine to the channel. In the starting position the rings rest, preferably, on the bottom of the magazine, said bottom being suitably inclined in such manner as to cause the rings, owing to their own weight, to effect an axial sliding movement on removing the ring next to the channel from the magazine. Preferably, also the end of the bottom directed away from the magazine is so inclined as to cause the rings to move on account of their own weight for instance with a rolling movement.

An embodiment of the invention applied to a device having four magazines and channels operating in parallel is shown in the accompanying drawings in which Figure 1 is a partial vertical section through the device. Fig. 2 is a horizontal View of the same, the protecting cap being removed. Fig. 3 is an end View of the device.

Referring to the drawing, the device 1 shown is supposed to be connected with the bodies are passed in a simple and reliable inlet end of a furnace. 1 denotes a frame supporting the magazines 2 and the channels 3 as well as the device passing the rings I 4 from the magazines to the channels. Each magazine 2 consists, in the embodiment shown, of a straight channel 'of angular cross-section (shown at 2 in Fig. 2) in which the rin s 4 are placed with the plane side surfaces bearing against each other, as shown in Fig. 1. Because of such a placing of the rings, the length of the magazine is reduced as far as ossible for a certain number of rings. ach magazine or channel 2 is at the inner end provided with a flange 5 connecting the magazine with the inclined rear wall 6 of the frame 1, the magazine thereby obtaining an inclined position enabling the rings to slide on the magazine. The magazine is adjustably attached to the wall 6 and provided with screws 7 with nuts serving to lock the magazine in adjusted position. The adjustment of the magazine is effected by means of a screw 8 screwed into the lower part of the wall 6 and provided with a hand-wheel 9. Thus the device may be used for rings of various sizes.

One end of the channel 3 by the aid of which the position of the rings is changed is connected to the upper portion of the wall 6 of the frame bounding the magazine, while the other end of the channel opens into the furnace. The foot plates 10 and 11 ofthe channel ,3 rest on the bottom 12 of the magazine, the channel being retained by means of screws 13 or the like. The bottom M of the channel 3 is curved in such manner that'the rings, when moving along slide downward obliquely in a plane form ing an angle with the first-named plane of movement. After that the rings thus are caused successively to place themselves on the edge at the foremost inclined portion of the bottom, as shown by stippled lines to the left in 1; the rings finally roll downward into the furnace,

The device for passing the rings from the magazine 2 to the channel 3., consists, in the embodiment shown, of grip arms 15, one for each magazine, secured to a rotatingshaft 16 journaled in the frame 1. The shaft 16 is actuated by any suitable moving device not shown in the drawing. The frame 1 and the channels 3 are provided with apertures 17 and 18 respectively enabling the arms to move as mentioned. To prevent the rings 4 from swinging out of contact with the grip arms 15, when moving upward from the 7 magazine, owing to the pressure exerted by 7 ited to such specific construction, since in'. fact the invention 18 susceptlble of a cons siderable range of variations Wltlllflthe handled and the subserved.

the subsequent rings, the portion of the channel 3 adjacent to the magazine is provided with a cover 19 serving as a guide for the rings. The part of the cover 19 adjacent to the magazine serves as a stopper for the rings preventing the ring located at the correspondingend' of the magazine from following the ring situated next to the channel on account of the friction. The cover 19 is supported by two screws 20 with nuts 21 journaled rotatably but not movable longitudinally in yokes 22 extending across the channel 3 thus enabling the cover 19 to'be adjusted in relation to the bottomof the channel according to various widths of the rings. Besides, all the channels 3 are covered by a removable cap 23 provided with an inspection aperture 24, which may be closed. by, a cover 26.

As mentioned above, the frame 1 and the magazines with the channels are supposed to be connected with the inlet end of a furnace'not shown in the drawing and are supported by suitable stays 25.

It is not to be inferred from the particular illustration and description herein given of the preferred construction of machine embodying the invention, that the latter is limscope of the appended claims, and in accordance with the specific annular objects to be particular purpose to be Having now particularly described and ascertained the nature of my said invention i at such outlet.
